A large interest in renewable energy systems has been developed to mitigate the green house effect. In Western Europe, the focus is thus, on wind power and especially on offshore locations, due to higher energy production, a longer expected life time and lack of suitable wind turbine sites on land. A DC cable is the preferred choice when connecting large offshore wind farms to the grid. The utilization of the Dc cables was enabled by the new HVDC transmission technology using voltage sourced converters. The offshore windfarms that are being bui ....etc

ENHANCED PERFORMANCE OF A DOUBLY FED
WIND-POWER INDUCTION GENERATOR AT WIND-
RANGE BOUNDARIES
ABSTRACT
The doubly fed induction generator (DFIG) is one of the largest generators used
with MW-class wind turbines. This paper focuses on the weak performance areas
of grid-connected DFIG-based wind turbines. Basically, the DFIG performance at
low wind speeds, close to the cut in speed, and around the full rating operation (in
the vicinity of rated wind speed) is investigated. For low wind speed region, the
c ....etc

A variable-speed controller, for an existing 225 kW fixed-speed wind power generator, is presented in this paper. A sensorless direct torque control algorithm-based controller is proposed for the squirrel-cage induction generator. Generator torque reference is derived based on sensorless maximum power tracking mode algorithm, up to the base speed of the generator. A three-phase front-end converter is used here to deliver the generated power to the grid with unity-power-factor operation at all wind speeds. This algorithm is based on direct activ ....etc

Wind – what causes it?, cont.
Pressure differences cause the flow of fluids (gases and liquids)
pressure is always measured relative to some reference pressure
Sometimes relative to vacuum  absolute
